>so I'm sure it has increased to (gut feeling) probably like 10% these days
That's consistent with the algorithmic estimate quoted in the article:
'the ReviewMeta algorithm labeled 9.1%, or 5.3 million of the dataset's reviews, as “unnatural.”'
I would say that's far from tiny, especially considering how many other reviews (at least in my own experience) have inadequate information in their text. A 3-star review that has only the words "It worked just fine but nothing special" is just as useless to me as a fake 5-star or 1-star review, whatever the fake text.
